Patent JP-H0479614-A (JP)
Title: A/d converter circuit
Inventor: NAKAJIMA HIROSHI
IPC: H03M1/20
Filed: 1990-07-23
Abstract: PURPOSE:To improve the accuracy of a digital signal by further A/D-converting an inputted analog signal after the signals are once A/D-converted, and amplifying the error between D/A-converted analog signals and the inputted analog signals. CONSTITUTION:When analog signals are converted into digital signals with 12-bit accuracy by using a 4-bit A/D converter 6 and D/A converter 8, the analog signals are A/D-converted and the data of the higher-rank 4 bits of the 12 bits are obtained in the 1st step. When the difference between the output of the A/D converter 6 and the original analog signals is taken after the output is D/A-converted, a 4-bit A/D conversion error is obtained. When the 4-bit A/D conversion is again made after the error is multiplied by 2<4> =l6, data of the intermediate-rank 4 bits of the 12 bits are obtained. By further multiplying the obtained error by 16, the lower-rank 4 bits are similarly obtained. When the higher-, intermediate-, and lower-rank data are added to each other through a shift register 11, digital data with 12-bit accuracy can be obtained.

Title: Lens transferring and positioning mechanism in automatic lens polishing device
Inventor: KOJIMA HIDEO
IPC: B24B13/005
Filed: 1983-10-15
Abstract: PURPOSE:To make a lens rotatable and swigable and as well to aim at surely securing the lens upon transferring, by fitting a cylinder tube onto a holder shaft incorporated with a piston, and as well by moving the shaft up down with the use of compressed air so that the shaft is released from and made in close-contact with a polishing holder. CONSTITUTION:In order to polish a lens L, when compressed air is introduced into a cylinder tube 4, a piston 2 slides upward so that a shaft 1 is pushed up in the tube 4. Accordingly, the tube 4 is released from a polishing holder head 15, and is locked to a piston lock nut 11 so that compressed air B will not flow into a holder 16, and therefore, the lens L on a polishing saucer 17 may be rotatably and swingably polished. Then in order to transfer the lens, when compressed air A in the tube is released, the piston 2 slides downward since the shaft 1 is pressed down by a compression spring 24. Accordingly, the lower end section of the tube 4 is released from the nut 11, and is connected to the head 15 so that compressed air B is communicated with the holder 16. Accordingly, when a vaccum condition is effected, the lens L is absorbed by the holder 16, and therefore, may be transferred.

Filed: 1984-09-14
Abstract: PURPOSE:To form a relined area having high compressive strength without reducing the stock line by spraying low-temp. curable refractories to a cooling means in the furnace wall part exposed as a result of erosion then press-feeding thermally curable refractories thereto. CONSTITUTION:An aperture hole 4 is drilled to the shell 1 of the eroded part and a spraying pipe 5 having the top end port opened so as to have directivity is inserted therein when a cooling pipe 3 is exposed as a result of the erosion in the wall of a blast furnace. The pipe 5 is rotated and the low-temp. curable refractories M1 are sprayed from the pipe 3 while the charge exists without reducing the stock line. The refractories M1 which cure at about <=100 deg.C are preferable. A press-feeding pipe 7 is attached to the hole 4 upon curing of the refractories M1 and thermally curable refractories M2 are press-fed therethrough. The eroded part is thus packed and relined by the refractories M1 and the refractories M2 and therefore the relined area having the high compressive strength is formed.
